Missed it by that much.



You only applied the -2 exponent to the denominator, when the square brackets are around the entire fraction. That is to say, your answer would have been (almost) correct if you had started with:



So, first apply the following rule:



Giving you:



Next apply:



(Which you did correctly where you applied it) Giving you:



But you still have one more step, and this is why I added the parenthetical almost earlier:

Apply:



Giving you:
